The teardown audit found the backup-stacking leak class across 4 more feature
modules (12 confirmed leaks); unmount() left document/window listeners, intervals,
and SSE subscriptions firing on stale controllers after navigation:
- admin: overview/ssh/peers/system each leaked a document click listener ->
AbortController + dispose() per page; admin unmount() aborts each.
- dashboard: the 1 Hz update-countdown interval + the LiveSystem view sub ->
stopUpdateCountdown()/detachDashboardLive(), registered via ctx.sub().
- tasks: constructor-started global live-log poller (discarded handle) -> stored
+ idempotent + cleared on unmount + re-armed on mount; per-task monitorTask
window listeners + interval -> tracked in a map, released on unmount.
- apps: app-tabbed reconcile setTimeout loop + watchdog window/document listeners
+ popstate -> per-instance AbortController + dispose() that clears the timer,
resets the guards, and unloads the active tab's Services intervals + log SSE.
All mirror the kernel's MountContext teardown discipline. 12 files, all pass
node --check. Backup (fixed earlier) re-confirmed clean by the audit.
